I got BTG: Armada in the Steam sale, and it only works for about 10-15 minutes of play before freezing up and crashing. I have no error logs, but can't actually get to the point of completing the tutorial (the crash point is a minute or two after manoeuvring round the first mine), or completing the first mission. It doesn't seem to matter how long I spend outside the game, or what I do in the game.

I'm running on Windows 10, with specs that exceed the minimum requirements. I don't know what's going on, but the Steam forums suggest there may have been a recent patch that's causing this. If so how do I roll back? If not, any ideas on what I can do?

After a close reading, it appears that your graphic cards are a bit under minimum requirements.This is probably why you experience those issues.At first, I'd recommend to lower the graphic settings but you still encounter crashes, you should probably change your graphic cards.
